   7 # * Fix that ugly hack with fix*
   8 #   Is there something in the shell like Perl's hashes? It could be nice to
   9 #   do something like "foreach $var (keys %fixes)" to associate fixes with
  10 #   file names so I don't have to track things all over the place
  11 #
  12 # * Fix also the code that iterates over user directories to include system
  13 #   directories in one run
  14 #
  15 # upgrade-windowmaker-defaults (0.3)
  16 #
  17 # * Handles upgrade to Window Maker 0.19.0
  18 #   Logo.Clip -> Tile.Clip (crashing)
  19 #
  20 # upgrade-windowmaker-defaults (0.2)
  21 #
  22 # * Handles keyname changes between 0.16.1 and 0.17.2

  45 # this one is for WMWindowAttributes

  47 # try to screen system accounts in the /etc/passwd file. If somebody
  48 # has a better method for doing this, I'm open to suggestions. Please
  49 # note that Debian Policy states accounts 0-99 are reserved for the
  50 # Project, and 100 onwards *could* be used by the local sysadmin, but
  51 # the default is 1000 and up

  86 I can try to fix certain configuration parameters that have changed
  87 between previous versions of Window Maker and this one, namely:
  88
  89  * WindowPlaceOrigin syntax change from "..." to (...)
  90  * Name change of Fiend to Clip
  91  * WMWindowAttributes: Logo.Clip -> Tile.Clip (crashing)
  92
  93 NOT fixing this could prevent Window Maker from starting. Please read
  94 /usr/doc/wmaker/NEWS.gz and /usr/doc/wmaker/changelog.gz
  95
  96 I will fix *both* the system defaults and each user's files.
